| 摘 要： | 研究了添加Ni的Al-Si-Cu基钎料真空钎焊LF21铝合金接头的力学性能、微观组织形貌.结果表明,采用添加Ni元素的真空钎料,可提高钎焊接头的剪切强度,其机制在于Ni元素能够改善LF21铝合金真空钎焊接头焊缝及其基体组织的分布.但随着Ni元素含量的增加,其钎料的熔点也有所提高.

| Abstract: | The mechanical property and microstructure of vacuum brazing joint of LF21 aluminum alloy after addition Ni to Al- Si Cu base brazing flux. The result shows that the cutting strength of brazing joint can be improved using vacuum brazing flux with addition of Ni. The mechanism is that Ni eleanent can improve the vacuum brazing joim and the distribution of its matrix structure. Melting point of brazing flux increased with Ni contem. |
